When the home becomes a battleground, siblings often fight a war no one else sees.

Sibling relationships can be complicated, especially in a toxic family dynamic where there is drama.

The toxic sibling relationship may be frought with competition, anger and hostility, condescending behaviors, and judgments.

Drawing from psychological frameworks, covert competition, emotional triangulation, or the pressure to play roles like "the scapegoat" are focused on.

In this video, I break down the psychology of how dysfunction can silently shape sibling relationships for years to come.
